Telling (the right) people about Delphi and how good it is (or rather: was), was something that has not been done since the very beginning. Not even Borland managed that. They advertised in Development magazines (and later websites), but not where those people who make decisions about the money to buy development tools (the C*Os of companies) would read about it. So when a developer asked his boss for the money to buy Delphi related tools, they had to tell him what it is (and who Borland, later Embarcadero is) and what the value would be for the money, because they had never heard these names.
It's even worse nowadays: We see Embarcadero endlessly blubbing on about how great their tools are to developers, but not going into specifics. That's the way you talk to the C*Os of companies, not to developers. But the C*O people do not read these posts because they just don't visit embarcadero.com and the Delphi blogs. So so they still haven't heard these names when it comes to investment decisions. And the developers don't read them because they don't get any interesting information from them.
